I was not able to find anything with a precursory search through CD (and I kinda assume you searched this before you started the thread, but I was curious), but I think if you look up truss design, you might find many more resources in that area. While truss bridges are NOT the same as gearbox or drivetrain plates, or whatever application for FRC, a lot of the theory behind truss patterns can be applied to pocketing patterns.

Another thing to check might be some of the softwares available for topology optimization. I haven't worked much with topology optimization, and I doubt many in FRC ever use it while designing their robots, but I imagine you could use topology optimization to design better pocketing patterns. And if you can do it in software, I'm sure you can find some guidelines or best design practices to write down.
